Summarise the Key Takeaways From a Book You Have Just Finished

You finish a good book, feel changed, and a week later remember almost nothing. Give it the title and your notes or impressions, and this pulls out the central argument, the three ideas you found most useful, and how they connect. Aimed at anyone who reads widely but wants the ideas to actually stick.
